Who has a successful example thank！

many attempts to understand exactly what you're trying to do and what errors you're getting have failed.

Please elaborate and give us as much information as possible so that we can actually help. What's the goal? what do you have when you start? what do you want to have when you're finished. what is the context of this script? are you writing a CEP panel or just a script to execute on demand for a given file?

We're happy to help.. But i doubt you'll find anyone who'll blindly dig through your code to try and figure out what you want to do or what kind of problems could feasibly be occurring.

care to share what the issue was? so that if someone else happens upon the same problem, they'll find this post and perhaps they'll be able to solve their problem as well.
